Any idea's on porting this to PBP?

Honestly..., I had to use the MCSP debugger to find the step -1. Saw that the FOR loop was never getting executed. Made it easy.

But a million years, you'd have got it.

Glad to help.

Darrel you are amazing!
I tried this out yesterday and it exactly what I'm looking for ( I am making a fuel consumption / complex odometer for my ancient Land Rover) and as I can't see close up without glasses, but have perfect long distance vision, a normal LCD display on the dashboard is quite useless and I had been considering large 7 seg display, but this is beautiful! Thanks a million.

PS: any tips on saving a counter on power-down? I was going to have the PIC running off big electrolytic for long power down delay, and then have one port sensing the instant loss of the (voltage divided) 12v ignition and then quickly write to EEProm, but would it be clever to use a brown out flag or something like that?

Thanks, but the credit goes to Scott Edwards on that one.

If you have a PIC with an LVD (LOW VOLTAGE DETECT) pin. You can use it to generate an interrupt when it detects the loss of power.

Then you can imediately set all pins to input and shut-down any on-chip peripherals to save current.

You should be able to run long enough to save about 8-10 bytes with just 10uf or so..

Hello Everyone,
This is cool. Anyone got an idea how to force this code to display 4 digits all the time? From 0000 to 9999? Scotts code works well. I tried dispVal = 0000 prior to the LCDOUT I,cgRAM statement and that did alright to start counter at zero and eliminate the initial display of a psudorandom 4 digit number at startup, I am sure it is simple, alas so am I .

Ahhh, I figured out 1 way, Preload with dispVal = 10000. I watched it count up until it overflowed and the zeros remained. Are there better ways ?

Just comment out this line ...

;            if dispVal < decade then blankIt

Added: Or better yet, make it ...

LeadingZeros  VAR BIT

            if (LeadingZeros = 0) AND (dispVal < decade) then blankIt

Then if you want leading zero's just set the bit.
